Cinnamon Queen Sexing Help!

[CrystalsCrazyCrew]

I'm a first time chicken mom, so I still have so much to learn. I bought these 4 chicks at Rural King. They were in the Cinnamon Queen bin... I was told they were all pullets and it seemed convincing at first, but as time goes on I'm starting to have doubts... None of them have tail feathers yet and I keep reading that they usually get them in the first week or two if they're pullets. Please tell me I'm not going to have 4 roos on my hands
The first picture of them together is when I brought them home, I'm guessing about 3ish days old? The second is today, assuming they're about 2 weeks old. They did not have a hatch date at the store.

Thanks for your help!

The tail feathers thing is hogwash.
Cinnamon queens are sexlinked, boys are white.

Feathering rates are somewhat random, agree with nuthatched, all girls

They're not Cinnamon Queens so sex linking is irrelevant. So is tail feather growth rates. That's not reliable.
Wait till 3 or 4 weeks old and check breast feathers. Males will feather in mostly black while females will have mostly reddish.
Day old pattern of duckwing chicks aren't as reliable for me as others would suggest but my guess going by those pics I'd say at least 3 of them are pullets. Possibly all 4.
